TABLE IX.

p-values obtained by a paired student t-test of ${\mathcal{C}}^{\mathit{SVM},\phi },{\mathcal{C}}^{C4.5,\phi },{\mathcal{C}}^{\mathit{ICD},\phi },{\mathcal{C}}^{CT,\phi ,\mu +},{\mathcal{C}}^{CT,\phi ,\sigma -}$ across 10 datasets, comparing 9 pairs of linear/nonlinear DR methods without feature pruning.
